You may also find 200 CFM or higher airflow computer fans but they are not very common and tends to generate a huge amount of noise. There are computer fans with 100 CFM or higher airflow too that delivers best cooling performance, and are mostly used in servers or harsh environments. Generally, fans with 70 CFM or higher airflow move a good amount of air and are labeled as high airflow fans. Therefore, a high airflow fan is also known as a high CFM fan. Higher the CFM value of the fan, the more air it will move in an open surrounding with no obstructions. It is defined as the volume of the air (in cubic feet) moved by the fan in one minute. The airflow of computer fans is measured in Cubic Feet per Minute (CFM). On the other hand, airflow fans are used as case fans, both as intake or exhaust fans and their main job is to move large volume of hot air out from the case which is generated inside the case due to components (GPU, CPU, RAM, HDD, etc.), but if it is used as an intake fan then it has to bring large volume of cool air into the case.

High static pressure fans may or may not generate high airflow, and even if they do then airflow is more focused with greater force so that air can penetrate in the small spaces and between the fins of the heatsink so that it can be cooled down quickly. There are also static pressure fans that generate high static pressure and are used on radiators, heatsinks or in restricted environments only. High airflow fans are not the quietest ones because of their higher RPM, they tend to make more noise compared to the quiet case fans that have relatively lower airflow, lower fan speed or RPM. These high airflow fans move a lot of air and they do a great job in cooling your precious components inside the case.

If you want the best cooling performance for your components inside the PC case then you need high airflow fans in your computer case. Thank you for supporting the work I put into this site!)
